This article is about the current B855 at Dunnet. For the former B855 (now A890) in Wester Ross, see B855 (Loch Carron).

The Ca', Brough

The B855 is the northernmost B-road on the British mainland, being the only road to Dunnet Head, the northernmost point. The road was originally unclassified but gained its number in the 1940s.

The road leaves the A836 in the small village of Dunnet, almost immediately making a sharp right to head north past St John's Loch, before reaching a TOTSO in Brough. The coast is very briefly met next to the sea stacks of Little Clett, before the road sweeps inland once more (and all too often into the cloud). It climbs in a series of short straights, with good visibility before a sweeping bend climbs up to Long Loch. Beyond the loch another bend leads to the car park at the end of the road, just a short stroll from the lighthouse at the northernmost point of the British mainland and the viewpoint on the knoll above.
